I thought I'd make a thread of its own on the topic for future use by all instead of buried inside my other thread. This is also a question to BT to double check and correct me, thanks Guru dude.
My starting gravity reading was 1.040, I took my 1st sample from the fermenter after 7 days, I have a final gravity reading of 1.002. As I understand it, this would normally not be a good thing but there's a mitigating factor that has to be considered, temperature. Living in S Fl and not having temp controls during fermentation, adjustments on the hydrometer readings have to be adjusted to 60 degrees, a table I found makes the calculation adjustment for ya.

My temps are approx 85-86, accordingly I need to add 0.004 to my final gravity reading in order to see if it's ready to bottle or to further ferment. My new adjusted reading is 1.006, it's a good number and even going to a 1.005 is good as well. I want to bottle on Wed, so this works great for me and it's still producing a good lick of bubbles.
Now I want to check my alc %, this is my cherry on this little task :) I found this to help me out. I hope I'm right and if not I know BT will steer me in the right direction.
ABV% Calculator
(OG - FG) x 131.25 = ABV%
(___* - ___**) x 131.25 = ___%
1.040-1.006 = 0.034 X 131.25 = 4.46225
